Seems this is the way of life in my world. Work Monday to Friday 8:30 to 4:30 at a customer site doing complicated configuration to get ready for a deadline. The odd pop over to be sure that things are flowing at the office. Get home Friday night and veg out for a few hours. Get up on Saturday and work the day in my store.
Then Sunday comes rest, coffee and do what I like for the day ... (Mostly , I have a partner so I have to consider her needs:)
Then Monday comes and we start all over again. "All my life is a circle!"
